.eAaDmER. RDS r-AND O A Y. Jj-Q I [NAS U i To qy Co rine r m" Be it 'lmo of Lynn," in the county ofEsseX and State of Massachusetts, have invented c'ertain"new and useful Improvements in 'Machines-for MoldingfCou'nters, &c., of which the'iolloivne' 'esr t on I This nvention relates to -machines for pressing'betweenfo posed molds o'r-dies articles ofleiatheronhke material which is" con formable to pressure, such as heel-stiffeners A or counters for boots and sho'es.

VVhile-the invention here shown azf embodied ina counter-molding machine, it is to be understood that ortions thereof,.a nd par- .ticularly those which "relate to means for forcing a movable mold or dietoward a fixed. mold" or die, first yieldingly until the. dies are i brought to a pressing relation with the inter posed material or blank, without regard. to the thickness of the latter, andare'then,

caused'to act p'ositivelyto-exert the desired forming pressure on the material, may be embodied in machines for pressing or molding soles-a'ndother parts of boots and shoes, &c.

The invention consists inthe several improvements hereinafterdescribed, and particularl pointed out in" the appended I claims.

To said cross-head is affixed a male mold or former 17, Which'is moved by the mechanism hereinafterdescribed toward andyirom the female mold, which is composed of two sections 18 18, loosely connected, as. hereinafter described, with the -fixed frame of the machine, the said/female-mold sections in this embodiment of my invention being adapted both to oscillate and to move,-

r'ectilinearly. As shown in F1g.. 1, the nvention is embodied 111' a ,twinmachine having two male molds, two female molds, and operating represents the frame of V cross-head which is mov-' able in guides 16 16,, affixed t'oqthe frame of mechanism causing-the molding oi twoco'uni I, ters durmg each cycle of movement oil the machine. description of one set of molds and the operating mechanism employed therewith will be understood as applying to' the entire organization shown in Fig 1. 19'represents aneccentric affixed by a key 20 to the shaft. 14, this part being hereinafter referred: to as the inner eccentric. 011 said inner eccentric is mounted loosely an outer eccentric having a hub 21 rigid-iv fitted to turn upon the inner eccentric, ,the 1 outer eccentric-being eccentric to the hub and to the inner eccentric. v The outer eccentric is divided at23 to enable it to be expanded and contracted, as hereinafter described, and thus alternately engaged with and disengaged from a ringer strap 2 L, which.surroundstlie outergeccentrici Said ring is formed on" a rod; or yoke 25, which engaged w'itlithe cross-head 15in suc'h. manner s'ro impart 1 motion thereto inthef direction of. the arrow as 1 1 1 in Fig. 3,.t'he engagementbetween the eccen- .ltric-r,od and the cross head beingin thiscase partially yielding and efleeltediby 'iiieaiis offa stud 26, adjustalily allis edlt oi 2'5, a-iid a spring 27, mounted n;the stud andbearin'g i terposedtr mesters spring onfa block 28 and the crossd e ad'.":hldvenient in the direction indicated applies pressure to the cross-head, first yieldingly throu h the spring 27 and then positively throug the stud 26 and block '28, the stud bearing on the 5 block. These details of mechanism for imparting movement from the eccentric-rod to the cross-head while useful in a counter :.molding machine may-be dispensed with and other means, omitting the spring-pressure,

substituted therefor. I

29 re resents a cam affixed by the key '20 to the s aft 14, the perimeter of said cam having a :recess. "30 and inclined cam portions p 33 represents a lever having a fulcrum .34 located in a slot 35 in the outer eccentric, one arm of said lever having a trundle-roll 36, which-rides on the perimeter of the ,cam 29.

37 represents-a spring whichis interposed between'the other arm of the lever 33 and a bearing 38, affixed -to the outer eccentric. When the cross-head 15 is moving forward and before the molds carried thereby come to a bearing on the workand press the latter aminstthe female mold, the arts occupy the jative positions shown in i ig. 3, the cam portion 3]. enga' ing the;lever 33 and exerting pressure throug said lever and the sprin 37 on the outer eccentric, thus rotating the atter on the i ner eccentrifl. This action continuesuntil'the malem'ol has come toahearing on the blank and he latter has been pressed by the male mold against the female mold. The spring 37 then yields and perv 5'. mits the cam portion 31 to force the inner end .of thelev'er 33 outwardly, as shown in Fig. 4. This movement of the lever causes a shoulder-39, thereon to strike a studv carried by an arm 40 on a rock-shaft 41, journaled in I ac.

the outer'e'cc'entric at the oint where the 42, which is caused by the turning of the i rock-shaft to bear on one of the sides of the division or opening in the outer eccentric 22,

thus expanding the latter and causing it to positively engage the inner surface of the ring 24. The said rin and the outer eccen '50 -t'ric thus become, in e ect, one part, so that they constitute a two-part eccentric ring or strap connecting the rod 25 and the crosshead with the inner eccentric 19, the continued rotation of which now imparts a positive movement through the said two-part ring or stra to the cross-head. The arrangement o the inner eccentric is such thatv its rotation does not move the outer eccentric in the direction required to move the crosshead in the direction of the arrow a; until the a ccentric has been. locked to the ring 24. ent. ofthesaid positive movement y the locking of the outer eccentric rig is determined by the form of the i entric'andi'issufficient to give the de- 'tter is divided; the rocks aft-being thus .sired positive pressure to the work between contracts out of locking engagement with the ring 34. When the cam portion 3'] again reaches the lever 33 it acts as before, throu h said lever and the spring 37, to rotate t e outer eccentric on the inner eccentric until,

the molds are both in operative contact'with the work, when the eccentric and ring are again locked together.

It will be seen from the foregoing that I have'made provision for initially imparting a yielding forward movement to the crosshead to bring the molds into operative con-' tact with the work and for then impartinga positive forward movement to the crosshea d. to effect the desired pressure, the extent of the yielding forward movement being determined by the thickness of the work. After the positive pressure has been ap lied and.

while the inner eccentric is moving backwardly a spring 43 retracts-the-cross-head and male mold and restores the parts to the position shown in Fig. 3.

The above-described mechanism maybe employed to move amovable mold or die to ward a fixed mold or diein a sole-melding or other analogous machine and may be em bodied in a' machine in which the movable mold moves vertically, in which case the spring 43 will not be required, the movable die being retracted by gravitation.

The female mold-sections 18- are provided at their opposed inner sides with formingfaces45; adapted to the exterior of a counter, the male mold 17 being correspondingly formed. The sections'18 are slidlngly connected at their. inner ends' with swinging guide-pieces 46, having hinge members '47 engaging complemental hinge members 48 on the frame 12. The guidepieces 46 have uid e-ribs 49, which engage grooves in the inner ends of the mold-sections 18. The guide-piecesare supported at the-outer exa tremes of ,their swinging movement by fixed stops 50, against which the guideepieces are held by springs 51. Said stops and springs cause the guides '49 to stand, preferably, at an angle of forty-five degrees to the path. of movement of the male mold.

52 '52 represent swinging ressure-blocks hinged at 53 to the cross-hea 15 and 'pressed by springs .54 against the oblique outer ends of the mold-sections 18, the latter being held yieldingly against the pressure5blocks and moved outwardly in the guide-ribs 49 byv whichis a plate movable in such proximity to the upper" surfaces of the 'molds as toen- 3 gage the edge ofthe blank which projects counter; 'Whenthe cross-head advances,

Said latch is provided with a stud 114, on which is mounted a roll 115, the purpose of which will be presently described. The latch is provided with a pin 116, to which one end the guide 61'. that the 's ring 110 shifts the slide, and the of {the ring 110 is connected, and with another pin 117, to which one end of the spring 108 1s connected. To the other end of .the

slide-bar a latchillS is pivoted at 11 9, said latch being provided with a recess in its lower. edge, near the free end thereof, said recess having a shoulder 120; IThe-toe 121 of the latch '118 is adapted tofabut the guide 61,

which is a fixed member, as will bepresentl descr1bed.- On said guide a'cam-plate 12-2 is mounted to coact with the roll 115 to trip the latch 11.2.- The latch 112. is provided with a toe 123. -.The' upright 105'is provided withia pin 124a The operation of this mechanism-is carries :the pin 107,.which' projects from the ears of the wiper, to a point whereit engages the'toe 123 of the latch 112, lifts. said latch, and as it continues to move along the slot 103 passes the toe and permits the latch to drop. .On the next movement (toward the i right) said pin 107 engages the upright side of the toe 123 and moves saidlatch and. the slide-bar (through the medium of the relatively strong spring 110) until the toe 121 of the latch 118 is stopped by contact with the end of the fixed guide 61. Oontinued'movement inthe same direction expands 'both springs and shifts the fulcrum or pivot 113 toward the other end of the slot 104. 'During this movement theejector is held in a posi-.

tion adjacent to the turned edge of the counter.. The next operation of the machine moves the cross-head 15 to the left and the molds Open, but theejector, of course, remains in the same position. This movement will carrythepin 124 to position to engage the shoulder 120 of the latch 1 18 and-lift said latch, so that its toe 121 will clear the end of This rcleases the slide-bar, s0

' ejector re eases the'counter from -.the in-ale mold and throws it free, so that it may drop into a suitable receptacle. The continued.

retreat of the Wiper causes the pin 107, which is still in engagement with the: toe 123 to carry the latch 112 and the ejector-slide toward the right until the roll 11 5,1iding up the cam 122 lifts the toe 123 clear of the pin 107, andfthen the long spring 108 restores theparts to the position shown in Figs. 13 and-14.

A carrier is provided for transferring a counter-blank from the'attend'ants station:

at-the front of the machine to-the openin between thedies' and for holdingthe bod y of the counter between the dies in such position 1 that the dies will close properly on said body. 1. The carrier is adapted to engage the portion 1 r of the blank which projects above the molds and subsequently forms the flange, the carrier being preferably adapted'to engage the ends of'said portion. As here shown, the carrier comprises a flat plate or bed 72, mounted on the swinging end of an arm which is .afiixed to a rock-shaft 73, which is journaled in fixed bearingsand rocked to oscillate the arm and hold the plate 72 alternat'ely projected from the machine-to receive a blank andin position over the dies 'to hold the blank between the dies.

The preferred counteron aging means comprise members 74', pivoteef at 75 to supports 80, hereinafter described, each member having a blank-receiving throat, preferably composed of a pair of fingers 76 77, forming one side of the throat, and a finger 78, rigidly the opposite side of the 't-hroat,;jas shown clearly in Figs. 8, 9, and 12. A stop-shoulder 79 at the inner end of the throat limits the insertion of the ends ofthe blankinto the throat. The. supports 80 are arms pivoted at 81 tolthe plate 7 2 and normally held by a spring 82, connecting said arms against stops 83, affixed to the plate 72. The members 74 are therefore adapted to swing toward and from each other in a plane parallel with-the plate 72. The fingers176, 77, and 78 are so arranged relatively to each other that the end of a blank 84 inserted in said throat will be-supported at one side by the fingers 76 and connected with the fingers 7 6 7 7' and forming too 77 and at the other side by the finger 7 8, the

blank being bent over, the edge of the finger 78, as shown in Fig. 9. This bending of the blank causes its firm frictional engagement 'with the fingers, so that there 1S I1O liability ;of displacement when the carrier is moved to locate the blank between the dies. The free dom of movement ,of tl1e-.m'e"mbers 74 vafforded by the pivotal connection of said members with the arms 80 andby the pivotal connection of said arms with the plate 72 enables the said members to engage and hold blanks ofvarious lengths and sizes. The e'ngaging members are enabled by the pivoted arms 80 to swing laterally or crosswise. of the male mold, so that the bent blank'can be deflected in either-direction laterally by contact with the male mold when the carrier is moving to its blank-presenting position. 1 In practice the operator-grasps the end portions of the blank, bends it, and pushes its ends into the throat-s of themembers' 74 74 until the ends of the blank abut against the s'houlde'rs 79,.the blank being by this operation bent over thefingers 78, as shown in Fig. 9.

The arm which connects the plate .72 with the rock-shaft 7 S is telescopic, so that it may be lengthened and shortened, thus permitting the' plate 72 and--the blank-engag ng sees members thereon to belnioved to'rvard the portion of the female mold by the a d Vance, o-f 'the male "mold'andcaus'ing b'la ke'ngaging members and the blank to a 5 Q dvance-with the m ale 'nioldlintil the blank bears." on the female mold. The telescopic constrnction of said'arm also. permits. he said 5 plate and blank-engaging members; to be nidyed backward from the closed molds by the advance of'the flahge formery the blank.- engaging members being thus detached from tlie'blank just "before the flange is wiped down 'by the flange-former. The said tele- 'sco ic' arm: comprises a section 86',v rigidly I 5 connected with the plate 72, and a section 87', rigidly connected; with-Ethe rock-shaft 73. The section '8'7iis' provided with uides SS', in which-the "section 863s longitu inally mov- "jiible in eitherdirection to' var y the length of; the arm' and permit the described longitudinalmoyeinent of the carrier; Wherehythe .car-

For instance the highest portions of the male mold I engage portions of the counter and tend to deflct port-ions of the counter before said counter is firmly gripped by the molds themselves.

' Y the holding members, of the carrier are tothe armwvhich swings iti' Counters also vary considerably in degrees of hardness and. in size even when they are supposed to be the same; and it is therefore difiicult to from the spirit of the invention.

' and'positive movements from fit them to. grippers or carrier members which hold them immovably while presented to the molds. The mounting of-thecounterholding members so that they will have the freedom of movement hereinbefore described enables them to retain their hold of the counters regardless-of the varying condition of the countersthemselves and of the movements-of the molds as said molds approach their final moldin positions.

.I do not limit myself to the details of mechanism shown and described and may variously modify the same without departing It is obvious that the counter-en aging members,- movable by the advance 0 a movable mold to permit the. engaging-members to hold the blank until it is in position to receive its final pressure, may be usedin a machine in which the male mold is fixed, the female mold having all the movements required to efliect the desired pressure. It is also obvious that the oeration of the sectional female mold and t e means, for opening and closing the same would be the same if the male mold Werefixed, the movability being confined to the female mold.

The ring-n, surrounding the outer eccentric,

may be considered a clutch member, since it is frictionally locked to the outerieccentric ing and using the same, althoughwithout having attempted to set forth all the forms in which it may be embodiedfor all the-modes of its use, what Iclaim is 1. In a molding or .pre'ssing machine, a.
